Can you tell me how you transferred Poco to your new machine Be careful that those transferred files aren't marked Read-Only.Also make sure not to install Poco into Program Files, since it's protected against changes.

I'm also on Win 7 - 64bit, but Barca Pro doesn't cause problems with any browser.

I installed Pocomail 4.8.0.440 from a fresh installation file. I didn't transfer any files from a previous installation except the address book through "recovery" . I installed Poco into Program Files(x86) in Windows 7 64bit. The message files etc. are in My Documents.

Yes, Chrome is my default browser.Also, besides any link in a message causing a crash of Poco, even the Pocomail web link in the help menu when clicked causes a crash as well as using view from browser option in the message menu.

I'm not sure what's going on, but maybe you could this. It doesn't hurt to try it.
